Heating EquipmentDHW-HIR-FPLRFURNACE-HIR-FPLRaccepts the U-name of a CURVE-FIT instruction that definesa linear or quadratic equation. That equation will be usedto correct the ratio (energy input/heat output) (DHW-HIR inthe PLANT-PARAMETERS instruction) of a domestic hot wateras a function of part-load ratio.accepts the U-name of a CURVE-FIT instruction that definesa linear or quadratic equation. That equation will be usedto correct the ratio (energy input/heat output) (FURNACE-HIRin the PLANT-PARAMETERS instruction) of a furnace, includingits pilot light, as a function of part-load ratio. Seediscussion of -HIR-FPLR.HW-BOILER-HIR-FPLR is the same as DHW-HIR-FPLR for a hot-water boiler(HW-BOILER-HIR in the PLANT-PARAMETERS instruction).STM-BOILER-HIR­FPLRCooling TowerTWR-APP-FRFACTTWR-FAN-ELEC-FTUTWR-RFACT-FATTWR-RFACT-FRTTC-CHLR-CAP-FTis the same as DHW-HIR-FPLR for a steam boiler(STM-BOILER-HIR in the PLANT-PARAMETERS instruction).accepts the U-name of a bi-linear or bi-quadraticequation. This is the inverse function to TWR-RFACT-FATand expresses the approach as a function of the ratingfactor and the wet-bulb temperature. It is normalized tobe the design approach at the design rating factor and wetbulb.accepts the U-name of a CURVE-FIT instruction that definesa linear or quadratic equation. That equation will be usedto express the tower fan electric consumption as a functionof the number of tower units per cell.accepts the U-name of a CURVE-FIT instruction that definesa bi-linear or bi-quadratic equation. That equation is thelogarithm of the tower rating factor as a function of theapproach temperature and the ambient wet-bulb temperature.It is normalized so that it is equal to 0.0 at the designapproach and wet-bulb temperature.accepts the U-name of a CURVE-FIT instruction that definesa bi-linear or bi-quadratic equation. That equation is thelogarithm of the cooling tower rating factor as a functionof the logarithm of the range, and the ambient wet-bulbtemperature. It is normalized so that it is equal to 0.0at the design range and wet-bulb.accepts the U-name of a CURVE-FIT instruction that definesa bi-linear or bi-quadratic equation. That equation willbe used to express the compression chiller capacity as afunction of condenser and chilled water temperatures whileoperating in the direct cooling, THERMO-CYCLE mode.V.45 (Revised 5/81)
